This 0.2 mL magnetic tube rack is useful for DNA/RNA separation using paramagnetic beads (e.g. SPRI).
The 8-well slot can hold tubes in both a high and low bead pelleting orientation (top and bottom), useful for washing pellets or pulling off elutions. I suggest a light colored filament for seeing the bead pellet easily.
Magnets can be force-fit into the print. I've used 6.35mm (diameter) x 6.35mm (length) cylinder magnets, specifically https://www.amazon.com/gp/product/B079MHJH23/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1.

I tend to block support generation for the magnet slots, to avoid having to do a post print clean-up. I've printed without any supports with good success.
Addition of magnets.
Force fit magnets into print. No glue necessary. If you're having trouble, I've turned the print on its side and tightened a wrench over the magnet until it slipped into the slot.
